I just installed Paul's IRS bushings and his much stronger Toe Link Bar system for my IRS and the cars feels much more solid in the rear with no wheelhop and my IRS does not move around side to side at WOT like it did with the stock Toe Bars. I was highly reccommended by a buddy of mine that put these on his car and said it was probably one of the best mods he has done to his car because of the more solid feel and the way it controls wheelhop alot better because these bars will not flex like our stock bars do. Just thought i would pass the info along!
